Morophon, the Boundless

Description

Morophon, the Boundless (CMM 1058) is a legendary shapeshifter creature from Commander Masters that has changeling, making it every creature type. As it enters the battlefield you choose a creature type, and spells of that chosen type you cast cost one colored mana of each color less while creatures you control of that type get +1/+1. Its five-color identity and commander-friendly cost-reduction ability make it a natural tribal commander and a deck-building focus for creature-type synergies.
